I was told about this a long time ago but didn't believe it.
Sure enough, at work we moved from one building to another and
one of our Sparc's hard drives wouldn't spin back up when it
was powered back on. A Sun technician did explain a "trick" to
try as a last resort:
-- Have one person hold the pizza box about an inch or two off
the table.
-- Another person turns it on and the first person *drops* it.
It works on occasion, long enough to make sure the drive is
backed up, of course !!
Now, why does this happen, especially in Sun equipment ?? They
use standard disk drives, don't they ?? It has something to do
with the lubricant in the motor and/or ball bearings remaining
"liquid" while the drive is spinning, but somehow solidifying
very quickly as soon as it's allowed to stop and cool down. Is
that correct ??
